CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 344,566, dated June 29, 1886.

Application filed November' 10, 1885.

To all whom it may concern:

Be it known that I, JOHN HENRY GLUEvnR, a citizen of theUnited States, residing at Albany, in the county of Albany, in the State of New York, have invented a new and useful Improvement in Corkscrews, of which the following is a specification. c

The object of my invention is to produce a corkscrew which will automaticallyfdraw a cork, and at the same time prevent the liquid in the receptacle from sporting out as the cork is withdrawn. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which*- v Figure lis an elevation of my cork-extractor with a part of the lower portion of the tube B broken and removed, showing the corkscrew A. Fig. 2 is a section of my cork-extractor, showing the screw-threads C C in contact with and meshing with the screw-threads cl d.

Similar letters refer to similar parts throughout the several views.

A is the cork-screw proper having an ordinary handle, a.

B is a hollow tube or chamber having the sides open, showing the spring E E, made so as to be placed over or around the mouth of the receptacle from which the cork is to be drawn.

C C are screw-threads cut upon the corkscrew.

D is a pawl fastened to the chamber B, and having sections of screw-threads d d in its upper end for the screw-threads C C to work into.

Eis aspring, with its lower end fastened to or resting upon some part of the chamber B, and the top so arranged as to be compressed when the 4corkscrew A descends into the cork.

My invention is used in the following` manner: The bottom of the chamber B is placed over or around the mouth of the receptacle from which the cork is to be withdrawn. The handle a being turned, the corkscrew A will Serial No. 182,391. (No model.)

descend into the cork in the same manner as an ordinary corkscrew, and at the same time the screw-threads C C will descend through their corresponding threads, d d,of the pawl D, thus compressing the spring E,and the same is held down in its compressed position by the pawl D, and when the corkscrew A is turned to a sufficient distance into the cork and the spring E is sufficiently compressed the resistance of the pawl D to the screwthreads C C is removed by gently pressing thelowerend of the pawl,so as to remove the parts d d ofthe pawl from contact with the screw-threads C C. The resistance thus being removed the force of the spring willdraw the cork, and the tube or chamber B will prevent the liquid from spurting out.

l do not claim as my invention the hollow cylinder B, arranged to iit over the mouth of a bottle, and having a spindle carrying a corkscrew passing through the cylinder; nor do I claim as my invention the use oi'a spring in cork-extractors for the purpose of automatically drawing a cork; but

Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

In cork-extractors, the combination of the tube B, adapted to be placed over the neck of a bottle, a corkscrew working inside said tube, a, screw-threaded shank or carrier which operates said corkscrew, a coiled spring bearing at its lower end upon the tube B and at its upper end against the shank or carrier, and a pawl pivoted to the tube B and having screwthreads upon its end which engage with the threads upon the carrier, all operating substantially as described.
